Dishwasher Won’t Drain? Causes and Fixes You Need to Know

A dishwasher that refuses to drain can quickly turn your kitchen into a mess. Standing water, unpleasant smells, and dirty dishes can make anyone frustrated. But before you rush to call for dishwasher repair, there are a few things you can check on your own.

This guide will walk you through the common causes and simple fixes for a dishwasher that won’t drain — and when it’s time to call a professional for dishwasher repair near me.

1. Check for Power and Cycle Completion

Start with the basics.

Make sure your dishwasher is plugged in.
Check if the breaker has tripped.
Confirm that the wash cycle is complete. Some dishwashers pause during cycles, leaving water temporarily.

If everything looks normal but water remains, move to the next step.

2. Inspect the Drain Hose

A clogged or kinked drain hose is a common reason for drainage issues.

Pull out the dishwasher slightly to access the drain hose.
Ensure the hose isn’t twisted or bent.
Detach it from the sink drain or garbage disposal and check for blockages.
Flush it with warm water to clear any debris.

If this doesn’t help, it’s best to have a professional handle the repair safely. Visit Repairmen.com for dishwasher repair service near you.

3. Clean the Filter and Drain Basket

Food particles, grease, and debris can build up in the drain filter and basket.

Remove the bottom rack of your dishwasher.
Unscrew the filter cover and take it out.
Rinse the filter under warm water with mild soap.
Use a brush or cloth to clean the drain basket below.

When filters are clean, water can drain smoothly again.

4. Check the Garbage Disposal Connection

If your dishwasher is connected to a garbage disposal, the problem might lie there.

Make sure the disposal is clear. Run it for a few seconds to remove stuck food.
If the dishwasher is newly installed, ensure the knockout plug inside the disposal inlet has been removed.

A blocked connection between your disposal and dishwasher prevents proper drainage.

You can rely on Repairmen.com for quick dishwasher repair and safe connection fixes.

5. Examine the Drain Pump

The drain pump pushes water out of your dishwasher. Over time, small food particles or objects can jam it.

Unplug the dishwasher.
Access the pump underneath the unit.
Check for obstructions and remove them carefully.

If the pump motor is noisy or not spinning, it might be defective and need replacement.

👉 Tip: Avoid handling electrical parts if you’re unsure. Call 833-864-6908 or book an expert at Repairmen.com.

6. Test the Check Valve

The check valve prevents water from flowing back into the dishwasher.

Remove the valve and check if it’s stuck or blocked.
Clean it gently using a brush.
Replace it if it’s damaged or not sealing properly.

Faulty valves can cause standing water even after the cycle ends.

7. Listen for the Drain Solenoid

Many dishwashers use a drain solenoid to open the drain valve.

During the drain cycle, you should hear a clicking sound.
If you don’t, the solenoid may be faulty and should be replaced.

This is a job best handled by trained technicians. Contact 833-864-6908 for fast dishwasher repair service near you.

8. Look for Clogs in the Air Gap

If your kitchen sink has an air gap (a small device next to the faucet), it might be clogged.

Remove the cap and clean any debris using a brush.
Reattach the cap and test the dishwasher again.

A blocked air gap prevents water from draining correctly.

9. Check for Faulty Float Switch

The float switch detects water levels in your dishwasher. If stuck in the “up” position, it stops the machine from draining.

Remove the lower access panel.
Gently lift the float and listen for a clicking sound.
Clean it to ensure it moves freely.

If it doesn’t click or move smoothly, the switch might need replacement.

10. Clean and Reset Your Dishwasher

Sometimes, all your dishwasher needs is a reset.

Turn off the power for 5–10 minutes.
Press the “Reset” or “Cancel-Drain” button (if available).
Restart the cycle to check if it drains now.

If the problem remains, you might need professional help. Contact 833-864-6908 or visit Repairmen.com for same-day repairs.
